Struct syntax::errors::Handler

pub struct Handler {
    pub can_emit_warnings: bool,
    // some fields omitted
}

Unstable (rustc_private)

A handler deals with errors; certain errors (fatal, bug, unimpl) may cause immediate exit, others log errors for later reporting.

Fields

can_emit_warnings: bool
